对我院完全性左束支阻滞伴波形正常化的室性融合波1例分析如下。1病历摘要男,72岁。因心悸胸闷就诊。心电图示(图1):窦性心律,HR91次/m in,Ⅰ、V5、V6导联呈宽阔、顶部粗钝的R型,V 1、V 2呈rS型,QRS波群时限≥0.12 s,并有继发性ST-T改变。第3个QRS波群较为细窄,前可见窦性P波;? A complete analysis of our hospital left bundle branch block waveforms with normal room for the fusion wave analysis of 1 case as follows. 1 medical summary male, 72 years old. Due to palpitation chest tightness. Electrocardiogram (Figure 1): sinus rhythm, HR91 times / m in, Ⅰ, V5, V6 lead was broad, blunt top R type, V 1, V 2 was rS type, QRS complex time ≥ 0.12 s , And secondary ST-T changes. The third QRS complex is relatively narrow, visible sinus P wave before;
